Benjamin Bloom created this taxonomy for categorizing levels of abstraction - thus providing a useful structure in which to describe Lesson Plan Components: Interest Approach, Discussion, Presentation, Demonstration, and Test Items. Content Goals start with an active verb. Note the 'Cues' below, which suggest active verbs that may be used when creating Lesson Plan Components. See the Example Lesson Plan.

Note: IPSI uses Bloom's work as modified by Simpson and Kratwold to create three domains: cognitive, psychomotor, and afective. The first, second and fourth levels of Bloom form the cognitive domeain. The third level of Bloom forms the psychomotor domain and the fifth and sixth levels of Bloom form the affective domain. Accordingly, content will be parsed into one of nine categories --- three levels of cognitive, three of psychomotor and three of affective. These nine categories are sufficiently precise so that prescriptions regarding instruction and testing can be aligned with the intent expressed in content goals.
